Demographic And Clinical Characteristics Of Patients Prescribed Proprotein Convertase Subtilisin/kexin Type 9 Inhibitor Therapy And Patients Whose Current Lipid-Lowering Therapy Was Modified.

PURPOSE: Our objective was to describe the demographic and clinical characteristics of real-world patients in the US with elevated low-density lipoprotein cholesterol (LDL-C) whose lipid-lowering therapy (LLT) ─ both proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitor and non-PCSK9 inhibitor ─ was actively modified. METHODS: This retrospective cohort study used linked laboratory (Prognos), pharmacy (IMS Formulary Impact Analyzer), and medical claims (IQVIA Dx/LRx or PharMetrics Plus) data. PCSK9 inhibitor-prescribed patients with LDL-C ≥70 mg/dL (multiply by 0.02586 for mmol/L) at the time of prescription were matched by LDL-C test date to patients whose non-PCSK9 inhibitor therapy was modified by intensifying statin therapy, switching statins without intensification, or augmenting with ezetimibe (N=12,345 in each cohort). Baseline demographics, use of LLT, LDL-C values, atherosclerotic cardiovascular disease (ASCVD) diagnoses and cardiovascular comorbidities, and occurrence of major adverse cardiovascular events (MACE) were assessed during the 2-year pre-index period. RESULTS: Mean age was 66.2 years in the PCSK9 inhibitor cohort and 64.1 years in the cohort whose LLT regimen was otherwise modified. Respectively, mean baseline LDL-C values were 150 and 121 mg/dL; 60.3% and 39.0% of patients had ASCVD diagnoses, and 9.6% and 5.1% had experienced a recent MACE. Prevalence of ASCVD diagnoses in the PCSK9 inhibitor and modified non-PCSK9 inhibitor cohorts, respectively, was 15.5% vs 9.1% for acute coronary syndrome, 20.7% vs 8.7% for coronary revascularization, and 22.2% vs 5.1% for possible familial hypercholesterolemia. In addition, 19.8% of patients in the PCSK9 inhibitor cohort were receiving both statins and ezetimibe vs 5.0% in the modified LLT cohort. CONCLUSION: Physicians are prescribing PCSK9 inhibitor therapy to patients with markedly elevated LDL-C levels who also have comorbid risk factors for adverse cardiovascular events. These results may be of interest to payers and policymakers involved in devising access strategies for PCSK9 inhibitors.

Patient-completed or symptom-based screening tools for endometriosis: a scoping review.

PURPOSE: The objective of this review was to evaluate existing patient-completed screening questionnaires and/or symptom-based predictive models with respect to their potential for use as screening tools for endometriosis in adult women. Validated instruments were of particular interest. METHODS: We conducted structured searches of PubMed and targeted searches of the gray literature to identify studies reporting on screening instruments used in endometriosis. Studies were screened according to inclusion and exclusion criteria that followed the PICOS (population, intervention, comparison, outcomes, study design) framework. RESULTS: A total of 16 studies were identified, of which 10 described measures for endometriosis in general, 2 described measures for endometriosis at specific sites, and 4 described measures for deep-infiltrating endometriosis. Only 1 study evaluated a questionnaire that was solely patient-completed. Most measures required physician, imaging, or laboratory assessments in addition to patient-completed questionnaires, and several measures relied on complex scoring. Validation for use as a screening tool in adult women with potential endometriosis was lacking in all studies, as most studies focused on diagnosis versus screening. CONCLUSIONS: This literature review did not identify any fully validated, symptom-based, patient-reported questionnaires for endometriosis screening in adult women.

A randomized, double-blind, placebo-controlled, fixed-dose, multicenter study of pregabalin in patients with generalized anxiety disorder.

Pregabalin is a novel compound under development for the treatment of several types of anxiety disorders. To obtain an initial evaluation of the efficacy and safety of pregabalin in the treatment of generalized anxiety disorder (GAD), we conducted a double-blind, fixed-dose, parallel-group, placebo and active-controlled multicenter 4-week study that compared 271 patients randomized to receive pregabalin 50 mg tid (N = 70), pregabalin 200 mg tid (N = 66), placebo (N = 67), or lorazepam 2 mg tid (N = 68), followed by a 1-week double-blind taper. The primary efficacy parameter was change from baseline to endpoint (last observation carried forward) in the Hamilton Anxiety Scale (HAM-A) total score; adjusted mean change scores on the HAM-A were significantly improved for pregabalin 200 mg tid (difference of 3.90 between drug and placebo; p = 0.0013 [ANCOVA], df = 252) and for lorazepam (difference of 2.35; p = 0.0483 [ANCOVA], df = 252), with the significant difference between the pregabalin 200 mg tid and placebo groups seen at week 1 of treatment (p = 0.0001 [ANCOVA], df = 238). Safety analysis, which included assessment of spontaneously reported adverse events, laboratory monitoring, and withdrawal symptoms, showed pregabalin to be generally well-tolerated. The most common adverse events seen with pregabalin 200 mg tid were somnolence and dizziness. They were usually mild or moderate in intensity and were often transient. Pregabalin-treated patients had a higher completion rate than lorazepam-treated patients. This study supports the hypothesis that pregabalin is effective and safe in short-term therapy for GAD. More studies are needed to determine the best dosing regimen to optimize efficacy and tolerability.
